IMPROVEMENT IN GIN-SAW-FILING MACHINES.

Speciticatibn forming part of Letters Patent N0- 150,809 dated May 12,1874; applicntion liled Manch 23, 1874.

T0 all whom it may concern Be it l;nown tlmt I, LEWIS MONROE ASBILL, 0fRidge, in tl1e county 0f Edgefield and Stute 0f Souh Carolina, hzweinvented a new und Ixnproved Gin-Smv-Filing Machine; und I d0 herebydec12ue that tl1e following is a full, dem, 2md exact deseription 0ft-l1e sinne, reference being had t0 the acconnmnying dmw ing forming apaa*t 0f t-l1is specification, 111 whioh 1 Figu1 1 is a side elevatioi1,und Fig. 2 a plan view.

'lhe invention relates generally to machin0s tl1at are usedt-ofacilitate the filing 0f gin-szuv teeth, and to supersedethe old meaus0f perfoiuning tl1e W0rk by band, but 11101e part-icu- ]arly t0 theimproved machiue 011 which a patent was granted to me 011 the 3lst 0fDecen1ber, 1872. T110 iinprovements consist 'in means forgiviug avariable adjustmenj: t0 the file-stroke, while the forw2ud end or poiut0f tl1e file is 11015 changed in osition. V

A represents the erank driving-wheel that operates a pinion, B hzwingthe crank-arm Z). T0 13116 wrist; 011 the' end of this arm a1e attaehedpitmen O, Which vibrate a leve1y D, and, through a eonnecting-strap, E,move the file-holder F in its guide-tube G. I n1ake the levers D D withthe end d perfomted ab sove1al points, and -on an ar0curve, so tlm'n phestrap E may be adjusted 1n01e nearly to 61 moxe remote fr0n1 the fulerumd, tlu\s regulatin g the throw 0f the file-holder, while the front ofthe file is thus alw-ays correspondingly adjnsted, so as t0 be carriedt0 the szune forward p0iut: m: every IGCiPIOO2IOII. 1;he g11id-tube G anoblique slot g, in which the shzu1k 0f the file-holder piu f slides. B ythis consruclsion I czmse ehe file t0 turn slight-ly 01' roll in itssocket-guide G as it moves, und 130 give t0 'the gin-tooth abriar-point. The object 0f producing this peeuliar point is to czu1sethe teeth t0 enter the cotton more rezulily and thus cut 01 break theber less, us

' well zus allow io 110 be 1nore easily cleaned.

Having thus described my invention, what I claim is+- The lever D,curved ab t-he end d, a11d 112W- 1'ng severa-l perfomtions, asdeseribed, t0 allow ehe throw 0f file-holder t0 be regulated witl1 01111changing the farthest p0int to whieh the end 0f the file will go at auchforward stroke.

'lhe above specification 0f my inven'tion Signal by me this3d day 0fMarch, A. D.
